Toubon law: when your documents must be in French
France's Toubon law makes French mandatory in a wide range of documents: user instructions, warranties, invoices, advertising, employment contracts and staff rules. Here is what the texts actually require, what they do not, and how to bring your documents into compliance without losing weeks.

What the Toubon law says
Loi n° 94-665 du 4 août 1994 relative à l'emploi de la langue française, known as the Toubon law, rests on a simple principle: in France, French must appear in certain documents. It does not ban other languages. It requires French to be there, and not to be pushed into the background.
To know whether a document is caught, look at who it is meant for: a consumer, the general public, a public body or an employee.
Documents where French is mandatory
Goods, products and services (article 2)
Article 2 makes French compulsory in the naming, offer, presentation, instructions for use and description of the scope and conditions of the warranty of any good, product or service, as well as in invoices and receipts. The same rule applies to all written, spoken or audiovisual advertising.
In practice, this covers:
- packaging, labels and product sheets;
- user instructions and manuals (see our guide on language requirements for technical instructions);
- warranty certificates and terms;
- invoices and receipts;
- brochures, catalogues and adverts;
- terms and conditions of sale describing the offer (see translating terms and conditions of sale).
There is an exception for the names of typical products and specialities with a foreign name that are widely known to the public.
Public signs and announcements (article 3)
Any sign or announcement displayed on the public highway, in a place open to the public or on public transport, and intended to inform the public, must be in French.
Contracts involving public bodies (article 5)
Contracts to which a public-law entity, or a private entity performing a public service mission, is a party must be drafted in French, whatever their subject or form. If you bid for a French public contract, your tender and the resulting contract will be in French.
The workplace (French Labour Code)
The law introduced rules now found in the Code du travail:
| Document | Rule | Reference |
|---|---|---|
| Written employment contract | Drafted in French; French explanation of any job title that can only be expressed by a foreign term; translation into a foreign employee's language at their request | Article L1221-3 |
| Staff rules (règlement intérieur) and documents setting out obligations or information needed to do the job | Drafted in French, translations allowed | Article L1321-6 |
| Collective agreements | Drafted in French | Article L2231-4 |
The consequence is direct: under article L1221-3, an employer cannot rely, against the employee, on clauses of a contract concluded in breach of the rule. And where the French version and the translation differ, only the text in the foreign employee's language can be invoked against them. For more, see translating an employment contract.
What the law does not require
- Contracts between private companies fall outside article 5, which only covers public bodies and those performing a public service mission.
- Other languages are not banned. Instructions can be multilingual, provided French is included.
- Official terminology is not binding on private parties. The Conseil constitutionnel (décision n° 94-345 DC du 29 juillet 1994) struck down the obligation for individuals and companies to use terms approved by the terminology commissions. It still applies to public bodies.
- Documents received from abroad or intended for foreign nationals are exempt from article L1321-6.
- The law itself does not call for a sworn translation. A careful French version is enough to meet the requirement that French be present.
Common pitfalls
- Instructions supplied in English by a foreign manufacturer. An importer placing the product on the French market must provide French instructions.
- French in small print. Article 4 requires that, where a statement is translated, the French version be as legible, audible or intelligible as the foreign one.
- A job title in English ("Key Account Manager") with no French explanation in the contract.
- Staff rules or safety instructions issued only in the group's language.
- A rough translation of the warranty, creating discrepancies between versions and a risk of dispute.
Bringing your documents into line, step by step
- List the documents given to customers, displayed to the public or handed to employees in France.
- Sort them by applicable rule: article 2, article 3, article 5 or the Labour Code.
- Identify the source language. Chinese or English instructions must be translated into French; French staff rules can be translated for your foreign teams.
- Use a subject specialist: warranties and contracts are legal texts, HR instructions are administrative ones.
- Check the layout: same size, same position, same legibility for the French.
- Keep dated versions so you can prove what was provided and when.

A worked example
A French company is taking on English-speaking staff. It wants to give them a translation of its staff rules and safety instructions, 4,000 words in total, from French into English at Professional level (1.8 cents per word). The quote shows €72, VAT not applicable (article 293 B du CGI).
If it also has German- and Spanish-speaking teams, it orders English, German and Spanish together: €216 before discount, a 30% multilingual discount (€64.80), so €152 in total. These are the prices shown on the quote on the day of writing; full details are on the pricing page.
When Manuce is not the right option
If an authority, a court or a foreign body requires a certified translation (judgment, civil record, Kbis extract, diploma), Manuce does not provide one: contact a translator sworn before a French court of appeal (traducteur expert près une cour d'appel). Our guide when is a sworn translation required will help you decide. Likewise, a scanned PDF without a text layer must be converted first.
What people ask us about this
Does the Toubon law apply to contracts between two private companies?
No. Article 5 only covers contracts involving a public body or a private entity performing a public service mission. Two private companies can therefore draft their contract in English. Employment contracts, however, remain subject to article L1221-3 of the Code du travail.
Can a product be sold in France with English-only instructions?
No. Article 2 of loi n° 94-665 requires French in the instructions for use, presentation and warranty of a product. The instructions may be multilingual, but the French version must be as legible as the others.
What are the penalties for non-compliance?
For products, services and advertising, décret n° 95-240 du 3 mars 1995 provides for a fourth-class petty offence (contravention de la quatrième classe). For an employment contract that breaches article L1221-3, the employer cannot enforce its clauses against the employee.
Do I need a sworn translation to comply with the Toubon law?
The Toubon law requires French to be present, not a certified translation. A careful professional translation is generally sufficient. If an authority or a judge asks for a certified version, you will need a translator sworn before a French court of appeal.
